 Thanks in advance.


I suggest you using a device based on dib0700, I got it working on
Linux = 2.6.35:

 Thank you Allan!

   Did this device that you use works in 1-seg? I think it is just full-seg!


Yes, it support both: 1-seg and full-seg.

In our device we use only 1-seg because your processor cannot decode full-seg.

Sure, here we go.


 I am trying to use an OV2640 camera with soc_camera.

 I'm using ov772x driver as base, but it needs too much modification to
 work with ov2640.

 I don't know that sensor specifically, but they can be quite different.


Yes, in fact ov2640 appears quite different compared to ov772x and ov9640.

 The OV2640 chip remaps all registers when register 0xFF is 1 or when it is
 0.

 This is not unusual. There are a few ways to implement this, for example,
 drivers/media/video/rj54n1cb0c.c uses 16-bit addresses, and decodes them
 to bank:register pairs in its reg_read() and reg_write() routines.


Ok, I will try to implement it this way, case nobody suggests me a
better approach.

I got mx27_camera from pengutronix tree and modified it to work with
kernel 2.6.32 (few modifications). I added platform data/device on my
board using pcm970-baseboard.c as example.

In the kernel config I selected:
CONFIG_VIDEO_MX27
CONFIG_SOC_CAMERA_OV9640


I noticed a strange behavior: the ov9640 driver is called before mx27_camera:

Linux video capture interface: v2.00
 Probe OK until now, going to ProbeVideo 
 Probing OV9640 
Parent missing or invalid!
Driver for 1-wire Dallas network protocol.
i.MX SDHC driver
usbcore: registered new interface driver usbhid
usbhid: v2.6:USB HID core driver
oprofile: using timer interrupt.
TCP cubic registered
NET: Registered protocol family 17
mx27-camera mx27-camera.0: initialising
 mx27_camera: IRQ request OK!
 mx27_camera: pcdev OK!
 mx27_camera: clk_csi OK!
mx27-camera mx27-camera.0: Camera clock frequency: 2660

 mx27_camera: probe OK until now!
mx27-camera mx27-camera.0: Non-NULL drvdata on register
 mx27_camera: soc_camera_host_register returned 0!

Then ov9640 returns error because icd-dev.parent doesn't exist.

Did you already see this issue?

 Sorry, I cannot help you with an out-of-tree driver, and generally I would
 expect significant changes when going to 2.6.32.


Right, I can post a patch to add mx27_camera on mainstream kernel
since Sascha (original author) let me do it.

Sascha, can I submit it?

If you have a board powered by i.MX27 and with a camera supported by

If you have all frequencies supported in your country you can the

 Argh, sorry, you pointed this in your previous mail.

 Too bad we don't have any sensor available currently in mainline to do a
 fast test.


Unfortunately my camera is not responding to I2C commands, I already
slow it down to 10kbps with no success. I can see on oscilloscope
i.MX27 send I2C commands, but the camera doesn't respond to it.

Then I tested using the MT9T31 driver and change the it to my I2C
commands, as I2C is failing I force the probe to return 0. But the
soc_camera still failing:

Linux video capture interface: v2.00

 As far as I know, video buffers are allocated in probe() function. Maybe you
 have a memory fragmentation problem and you need to move buffer allocation
 to init().
 We have faced this problem many times in the past.


Hmm, great Javier, in fact it could be the issue!
